Start at the Champs de Mars car park in Briançon.
(S/E) Take Chemin des Salettes at the intersection with the N94 (a very small street that climbs between the restaurants "La vigne" and "Mamma Mia") opposite the car park. Arrive at Chemin des Fontaines (car parking available).
(1) Turn right onto the track leading to the old Fort des Salettes. Before the first bend, take the well-marked path on the right to leave the track.
(2) Without entering the fort, take the path that climbs to the left (follow the signs for Croix de Toulouse). This is a pleasant climb. Reach the summit of Croix de Toulouse. Enjoy the view of Briançon and join the track that climbs northwards.
(3) Follow this track. At the end of the track, without going as far as the small antenna relay station, take theGR®5Ctrail on the left and follow it until you reach a small abandoned house/sheepfold. From here, you can see the Écrins glaciers. Continue to the Enrouye blockhouse.
(4) Continue on the path that passes to the right of the building to go directly to the Serre des Aigles via a climb that becomes steeper on more rugged terrain.
(5) Once you reach the ridge, take your time, be quiet, and the eagles will come to meet you.
To return, take the same path to the crossroads of the trail and the track just before the Croix de Toulouse.
(3) Leave the path that leads to the Croix de Toulouse, which you took to get there, and continue along the track on the right for about 60 metres. Turn left onto a small path that leads into the forest and continue to the crossroads at an altitude of 1846 metres.
(6) Take a small path on the left (there is a sign) and follow the signs for "Briançon par le bois de la Pinée". The path is quite steep on the way down. You will arrive at the Chemin des Fontaines track.
(7) Take it on the left to return to the Chemin des Salettes crossroads.
(1) Turn right onto the path to return to the starting point (S/E).
